Hey guys, new to the forum and I got mucho problems. Long time coming has been a clutch job on my 88 f150. Started having problems getting into 2nd gear about a month ago and two weeks ago it finally left me on the side of the road. Tried to drop down from third to second and it wouldn't go in any gear. Finally I got it into third but I couldn't get it out of gear so I pulled over. Got the truck into reverse after that but it would only back up four or five feet then the wheels/transmission would lock up. I could keep backing up like that but only four or five feet at a time.
Now this week I finished up a clutch job on it. First I replaced the clutch disc, pressure place, slave/throw out bearing assembly, pilot bearing and the hydraulic clutch line. Got everything together and down the road and it does the same thing. Take off from the stop sign and it won't go into second gear. Pull over and tried to back up and the wheels/transmission lock up again. Got it into first and tried to drive home but it still wouldn't go to second and this time wouldn't go back in first. Also at the time I'm thinking the clutch is stuck engaged because it will only idle with my foot on the clutch pedal. Once I start to release the clutch it bogs down as if the brake is on with it in gear. Yes I'm sure it's in neutral lol.
I tow it home and replace the clutch master cylinder this time and when I turn the truck on its the same thing with the clutch. Truck will idle while I have the pedal pushed in but once I start to let it out the truck begins to bog down. This morning I disconnected the drive shift to see if the rear end would spin freely and there's no problems there.
It only makes sense to me for the problem to be in the tranny but I don't know where to start.
Also with the truck off I can put it in first, second and fifth but not third or fourth. Maybe this is irrelevant but thought I'd add. I haven't tried reverse

Thanks for the help guys, I need my truck back!
